Does it have to be either/or, or can it be “YES!” to both?
Wouldn’t be that surprised to see the ocean scenario as a contributing player.
Should have seen the “erosion” readings I got from a slurry sample decades ago.
I used a probe in a water/ore-particle slurry that was connected such that the hesitance of the probe was monitored, with the resistance change as the probe wore away being used to calculate the projected erosion of pipeline to carry the slurry from an iron mine to the mill. Problem was, the slurry was rotated past the probe in the vessel, and it contained magnetite.
Rotating magnetic particles and a steel probe = generator! The engineers I was working for had to design a new test method.
This could be a somewhat analogous macro-situation.
Thanks ApplegateRanch.
Speaking of sediment, I wonder if I posted that other article on here...
What did they do for the new test method?
Cheers!
